So I have an application that I'd like to change the icon for. If I drag and drop the new icon into the app's
Contents/Resources/ via the GUI, the app updates ok.
However, if I
cp the icon in the terminal the icon doesn't update, and the original icon is still displayed or a slightly broken version of the original is shown.
What else do I need to do to allow the .icns to be updated via the terminal (I need to be able to script this for a project.)
